What other work could I do?

You obviously have a grasp of the English language. You could be a blogger, or sell your writing services on websites like Elance.com or Odesk.com. Not only could you pull in a little bit of extra income, but you will also be adding to your resume of talents. Plus, getting good feedback from your employers will continue to be the gift that keeps on giving, so you can revisit this line of work year after year (during breaks and such).
